I am using MSYS2 (Mingw-w64 64bit) on Windows8.1.

And I try to install pretty_midi, a python package for midi manipulation.

At first, I typed

pacman -Ss pretty_midi

but there was no reply.
So I typed

pip install pretty_midi

then many messages appeared and at the end,

 removing: _configtest.c _configtest.o

the system tried to install numpy, and by this reason,

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

it stopped.
I searched for python-dev, but it seems to be no package corresponds to it in pacman.

I googled a lot, but I can't find the exact answer.

How can I solve this, and install pretty_midi on my MSYS2 system?

Thank you.
